Does the ``??`` operator use shortcircuiting?

Question

Does the `??` operator in C# use shortcircuiting when evaluating? var result = myObject ?? ExpressionWithSideEffects(); When ``myObject`` is non-null, the result of ``ExpressionWithSideEffects()`` is not used, but will ``ExpressionWithSideEffects()`` be skipped completely?

Answer 1

Yes, the rest of the expression after the ?? operator will not run at all if the left-hand argument is not null.
